My invention aims to provide a radiator of small thickness and height adapted .to 'be placed on the base of a wall or in s1m1lar situations where economy in the said dimensions is desirable and where, generally, space of considerable length is available. The accompanying drawings illustrate an embodiment of the invention.

Fig. 1 is a front elevation of a portlon of a radiator;

Figs. 2 and 3 are sections of the same on the correspondingly numbered lines;

Fig` 4 is an elevation of the complete radiator;

Fig. 5 is an end view illustrating frriodiiication.

Referring to the embodiment of the invention illustrated, the vessel for the steam or other heating medium comprises al pipe arranged in two substantially parallel lengths 1 and 2 connected by a bend 3. They are approximately horizontal, or they may be slightly inclined to facilitate drainage and circulation. The end of the upper length 1 is connected through admission valve 4 to a pipe 5,

and the. end of the length 2 is connected through an outlet valve 6 toa pipe 7. The two lengths of pipe are arranged 1n the same vertical plane and as close together as the total height of the available space requires.

A radiating structure is arranged in contact with the pipe, of a total width which iscomparatively small and of a height to .extend slightly above and below the pipe. Preferably, but not necessarily, the pipe 1s arranged on the outer side of the radiating notches 12 and 13 (Fig. 3) to receive the pipes RADTA'roB 1925. Serial No. 42,908.

1 and 2 so that these shall be flush with the outer face of the radiating structure.

A coverplate 14 is mounted on the front of the radiating structure and the pipes. It serves to conceal the radiator, to provide addltional radiating surface, and to assist in forming lues which produce'a ygood circula-- tion of air. It may be welded, soldered or otherwise attached to the corru ated struc.- ture and to the pipes l and 2. t its lower end 15,-it covers the pipe 2 and leaves the corrugated structure projecting somewhat lower to facilitate the entrance of cooled air from the floor 16 as indicated -b the arrow. At its upper end, it has a curved flange portion 17 which is bent inward and extends up in front of the corrugated structure, holding the air currents in the latter so that they pass out in the direction of the arrow. The spaces enclosed between the plates 8 and l0 and the front plate 14 form flues closed in vhorizontal section. Similarly, the adjoining spaces between plates 8 and 11 and the face 9 of the wall form approximately closed vertical flues. Thus the cooled air from the iioor is heated and rises through these flues and is exposed therein to a very considerable radiating surface and for a long enough time tobe. heated very efficiently. The plates may be made of copper which is a rapid conductor of heat and is most etlicient in heating the air passing over it. Though this is a comparatively expensive metal, the plates may be made very much thinner than steel or lron plates, the structure being so well braced by its shape as to have all the requisite strength. The pipe also may be of copper or brass for greater efficiency; or the pipe, and also the radiating structure, may be of iron or steel. The complete radiator including the pipes and the flues formed by the radiating structure, is a unitary transportable structure, as distinguished from radiators made of parts which are separately built into the wall of a room.

A radiator of this type may be made of small height, say six or eight inches and elongated sufficiently to secure the desired effect. Such a radiator, although the heat units transmitted to a given column of air are less than if the same column traversed a radiator of the usual considerable height,

will make up the 'required number 'of heat units by its length and at the same time will maintain a better circulation of air in the room because the total cross-section of the columns of ascending air will be greater than Y out into the room a forwardly curved shield 19, Fig. 3 (or 20, Fig. 5) may be fastened to the wall back of the upper part of the radiator and projecting above it and outward into the room.

The radiator may be mounted in various ways. There is usually a curve or molding in the corner at the bottom of the wall which might interfere with the placing of the radiator close against the wall'if it were carried on the usual supporting feet. -I prefer to fasten it to the vertical face of the wall, so that it can more easily be brought close up against the wall. For this purpose, I may use strips 21 and 22 fastened to the top and bottom ofthe inner face of the radiator and fastened at their ends to the wall by means of screws 23 or other fastening devices according to the character of the wall.

In Fig. 5 there is illustrated another method of mounting the radiator. It is shown in connection with the radiator set in a recess,'but may be used also for the outside type like Fig. 3. The shield 20 is extended either in a continuous plate or with openings to llighten it dow'n the back of the radiator proper to form a protecting sheet 21 and is provided at the bottom with fianges or feet 22 through which screws 23 may be passed to fasten the radiator directly on the floor. An additional set of screws 24 may be provided at the upper portion of the plate 21 and shielded somewhat from sight by the front plate 17, fastening the radiator back against the wall. The vessel for the heating medium may be a single length of pipe or may be more than two lengths. For example, in Fig. 5, I have shown the pipe in four lengths 25, 26, 27 yand 28. The diameters of the pipes may be varied inversely with the number of horizontal lengths used. And vesselsof other shapes than the bent pipes described may be used. Also other elongated heatin elements of small cross-section may be used instead of the pipes.

The radiator may be equally used for cooling air by circulating cold brine or the like through the pipes so that the latter 'become a heating element only inthe negative sense,

' to the outside of said vessel and constituting a radiating structure including vertical plates extending rearwardly from said vessel but not beyond the forward facethereof, so that the radiator may be placed against a vertical wall with the vessel remote from such wall.
